[PATCH] crypto: ccp: Don't initialize CCP for PSP 0x1649

by Mario Limonciello

A number of platforms are emitting the error: ```ccp: unable to access the device: you might be running a broken BIOS.``` This is expected behavior as CCP is no longer accessible from the PSP's PCIe BAR so stop trying to probe CCP for 0x1649.

That is, once armed it remains armed causing the CSC coeff/offset registers to become effectively self-arming. CSC coeff/offset registers writes no longer disarm the CSC, but fortunately register read still do. So we can use that to disarm the CSC unit once the registers for the current frame have been latched. This avoid s the self-arming behaviour from persisting into the next frame's .color_commit_noarm() call.

[PATCH STABLE 5.15.y] Reduce IPI overload when multiple CPUs cat /proc/cpuinfo.

by Imran Khan

On large systems with few hundred CPUs, when applications on each or most of these CPUs read proc/cpuinfo we get an IPI storm and situation gets worse if one of the CPUs can't respond to these IPIs timely. commit f4deaf90212c ('x86/cpu: Avoid cpuinfo-induced IPI pileups') addresses this but in the following call chain: show_cpuinfo | |-- aperfmperf_get_khz | |-- aperfmperf_snapshot_cpu aperfmperf_snapshot_cpu gets invoked with wait=true and this means we endup doing a smp_call_function_single to destination CPU, even if its ->scfpending is set. Avoid this by making sure that even with wait=true, IPI is send only if ->scfpending is not set. Signed-off-by: Imran Khan <imran.f.khan(a)oracle.com> --- I am trying this approach (assuming that its okay) to avoid backporting multiple upstream patches to fix this single issue.

[PATCH] ALSA: hda/hdmi: disable KAE for Intel DG2

by Kai Vehmanen

Use of keep-alive (KAE) has resulted in loss of audio on some A750/770 cards as the transition from keep-alive to stream playback is not working as expected. As there is limited benefit of the new KAE mode on discrete cards, revert back to older silent-stream implementation on these systems.

[PATCH] ceph: do not touch cap when trimming the caps

by xiubli＠redhat.com

From: Xiubo Li <xiubli(a)redhat.com> When trimming the caps it maybe queued to release in the next loop, and just after the 'session->s_cap_lock' lock is released the 'session->s_cap_iterator' will be set to NULL and the cap also has been removed from 'session->s_caps' list, then the '__touch_cap()' could continue and add the cap back to the 'session->s_caps' list. That means this cap could be iterated twice to call 'trim_caps_cb()' and the second time will trigger use-after-free bug.

[PATCH] ring-buffer: Prevent inconsistent operation on cpu_buffer->resize_disabled

by Tze-nan Wu

Sometimes, write to buffer_size_kb can be permanently failure if we change the cpu_online_mask between two for_each_online_buffer_cpu loops in function ring_buffer_reset_online_cpus. The number of increasing and decreasing on cpu_buffer->resize_disable may be inconsistent, leading the resize_disabled in some CPUs becoming none zero after ring_buffer_reset_online_cpus return. This issue can be reproduced by "echo 0 > trace" and hotplug cpu at the same time. After reproducing succeess, we can find out the attempt to write to buffer_size_kb node failure every time. This patch prevent the inconsistent increasing and decreasing on cpu_buffer->resize_disabled by copying the cpu_online_mask at the beginning of the function. But I wonder if there's any side-effect of this patch, since the behavior changed, if we turn on a cpu between the two loops, reset_disabled_cpu_buffer() of that cpu won't be run as before, meaning the cpu_buffer on that cpu just awake will not be cleaned up.
